I've been back and forth on this game so many times. Got it way back, when it only costed a few bucks. It was always a pain cause each time I came back the texture packs would get rearranged and renamed. But, anyways, welcome back and hope you enjoy the new features.
Sure, it'll be a little while though as I don't have the fastest upload speed. Also I recommend deleting files that you did not edit in the folders to make it quicker for others who do not have fast internet connections to download.
